UNITED STATES PATENT WILLIAM L. PARMELEE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO ALFRED G. REX, OF SAME PLACE.

SKATE-CLAMP.'

ESPECIFICATION forming part of Letters Patent No. 380,456, dated April 3, 1888.

Application filed January 18, 1888. Serial No. 261,144. (No model.)

To all whom, it may concern.-

Be it known that 1, WILLIAM L. PARMELEE, a. citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Skate-Clamps, of which the following is a specification.

My invention relates to improvements in skates; and the object of my invention is to construct a skate that can. be cheaply manufactured, and at the same time have a secure fastening, and can be readily adjusted to fit diiierent sizes of shoes, as fully described hereinafter.

In the accompanying drawings, Figural is a side View of askate, showing my improved clamping device. Fig. 2 is a plan view, and Fig. 3 is a detached perspective view of the cant lever.

Referring to the drawings, A is the runner of the skate, B the foot-plate, and D the heelplate, attached to the runner in any suitable It should be understood in the outset, however, that my clamping mechanism maybe attached to a roller-skate as well as to an ice-skate.

E is a heel-clamp having a tongue, 9, which is adapted to slide in ways (Z on the under side of the heel-plate D, and is provided with an upwardly-extending lip, c, which engages with the front of the heel, while the lugs d on the rear of the heel-plate grasp the rear of the heel.

F F are two clamp-levers having slots ff, adapted to which are screw bolts or rivetsb b, secured to the soe-plate B. These levers F are on the under side of the sole-plate and have upwardly-extending lugsf,which grasp the sole of the shoe. The levers F F are pivoted by pins 9 to a crosshead, G, which is made in two parts, and fits snugly around a nut, H, adapted to a threaded stem, '5, of a plate, I, an opposite threaded stem, '5, on which is adapted to a nut, J, which is con fined in a cross head,j, connected to arms 6 bent down from the heel-clamp E. The plate I has a circular opening, to which is adapted an eccentric, K, forming part of or secured to a lever, It, the latter being pivoted byascrew-' proximate to the size of the heel and sole of the shoe, this being their normal adjustment. When the lever is is in the position shown by dotted lines in Fig. 2, ample opportunity is afforded for placing the skate in position on the shoe, the clamps being clear of the sole and heel. \Vhen the lever k is turned to the position shown by full lines in Fig. 2, thelugs f will be drawn together and the lug 6 moved rearward, so as to clamp the skate tightly to the shoe, the eccentric occupying such relation to the pivot-pin that the strain upon the clamps tends to throw the lever inward. By merely moving the lever to the position shown by dotted lines, however, the skate is released. Thus it will be seen that a very effective, cheap, and quickly-adjusted clamping mechanism is formed, the central bearing, M, for the plate I rigidly securing the clamping devices to the skate and preventing the usual annoying rattling of the parts.

I claim as my invention 1. The combination, in aheel and sole clamping mechanism for a skate, of the soleclamping levers, the stationary heelclamps, the sliding heel-clamp connected to the sole-clamps, a plate secured to or forming part of said connection, an eccentric pivoted to the body of the skate and adapted to fit an opening in said plate, and a lever for operating said eccentric, all substantially as shown and described.

2. The combination of the sliding heelclamp having a nut, sole-clampinglevers, also having a nut, 21. plate, I, having a threaded stem adapted to the nuts, and an eccentric adapted to an opening in the plate and provided with a suitable lever, substantially as and for the purpose set forth.

3. The combination of the clamping-levers F F, the cross-head G, to which the clampinglevers are pivoted, anut, II, confined longitudinally to said cross-head, but free to turn therein, a plate, I, having a threaded stem adapted to said nut, and an eccentric pivoted to the body of the skate and adapted to act upon the plate I, all substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

VVILLIAM L. PARMELEE.
